Most technology creators would consider a seconds-long test a bitter disappointment, but it's a rousing success in the world of fusion energy. According to Phys.org, the Korea Superconducting Tokamak Advanced Research (KSTAR) device recently set a world record by maintaining its plasma at a super-hot 180 million degrees Fahrenheit for 20 seconds. That may not sound like much, but no previous fusion machine lasted for more than 10 seconds in those conditions even KSTAR held out for just eight seconds in 2019.


The key was to improve the Internal Transport Barrier that helps with plasma confinement and stability.


There's a lot of work left. KSTAR's ultimate goal is to run non-stop for five minutes at the extreme temperature by 2025. The breakthrough is an important step in that direction, though, and could prove vital if fusion reactors are to become a practical reality. That, in turn, could help the planet by further reducing the dependence on coal and other CO2-heavy energy sources.
